Traveling alongside the Waihou River, the track winds through wetlands, across rolling pastures and past small waterfalls to the turquoise water of the spring.

Flowing at a rate of 42 cubic metres per minute (9240 gallons per minute), The Blue Spring could fill a six lane, 25 metre swimming pool in just over 12 minutes. It maintians a constant 11°C in every season.
